SPECIFICATION forming part of Letters Patent No; 528,774, dated November 6,1894.

Application filed January 14, 1893. Serial No. 458.339. (No model.)

To all whom it may concern.-

. Be it known that I, FREDERICK N. GARD- NER, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented a certain new and useful Improvement in Shaft-Hangers, of

which the'following is a specification.

.' The objects of my invention are to provide simple, ready and efficient means for adjust 1o ingthe "tension of belting applied to the pulleys upon counter-shafts; to provide for advention is adjustably. supported or suspendedv from a bracket onceiling-plate, and tosnch end it is hinged to the same wherebyvit can be swung to an extent to position it with refereuce to the required tension of the belting. The shaft hanger thus arranged fora'djustable locking means, and as a matterof further and-special improvement, a locking device is provided which adapt-s1 itself to the adjustment of the shaft hanger, and therebypermits the latter to be swung to and be held at-any desired angle, with referenceto requirements, without detaching the lockingv device from the hanger. The locking device is also applied so as to eifectiv'ely hold and steady the hanger, and to such end it is connected with the latter whereat the hanger is pivoted orfulcrnmed, to insure effective resistance against the pull of the belting.

The shafthanger carries an adj ustablebel tshipping device which is operated by a rack and pinion movement, and the spindle of the,

pinion is operated by a handle having a flexiible or universally jointed connection with said spindle so as to permit the handle to hang vertically, regardless of any adjustment 'the door, to

able swing, is held in its adjustment by suit at a point sufficiently remote from thepoint' on the part of the hanger, and also soas'to permit-an operator standing for example upon deflect the handle with reference to his position, and thereby conveniently ma-. nipnlate the same.

Various details constituting matters offurther improvement are hereinafter fully set forth.

-In the accompanying drawi'ngs, Figu-re 1' represents the shaft hanger in perspective. Fig. 2 represents the opposite side of-the same in elevation and on asomewhat larger scale. Fig. 3"also represents the same in elevation, the'view from Fig. 4 is a vertical section through the bracket or ceiling-plate, hanger, locki ng a'point to expose'the. ends of the counter shaft, and shipper. rod.

belt-'shipper,with the lower portion 0fthe handle for the beltshipper removed for con} venience of illustration. Fig. 5 is asection taken centrally 'and longitudinally through I the counter-shaft and pulleysthereon;

- Thev shaft-hanger A is pivotally hung or hinged'so' as to be versely to the pnlleyor counter-snail; which it carries. The shaft-hanger is adjustable in this. said movement and hence 'is supported or suspended for adjustable swing,-in.whi ch way it can be adj listed to any desired degree of inclination.

Broadly considered, meanssuitable forlockingtl e shaft-hanger capable of swing trans in position, and so, far as Ijamaware I ain the first to provide a shaft iha'nge'r having an. adjustable swing [and carrying a countershaft and belt-pulleys, whereby, by varying the inclination of the shaft-hanger, the belting can be tightened. Asamatter of further improvement however, I provides. locking device consisting of an adj ust ableconnection B arranged between-the shaft-hanger and such overhead support-orfixture as the shaft hanger may be suspended from.

The shaft-hanger is at its upper end hinged or pivoted to a suitable bearing 0 which-forms a bracket or ceiling plate adapted for attachment to the'c'eiling, girders or other support or fixture arranged upon the wall or other-- wise-suitably disposed within-the building where power is employed.

in order to desired extent, the ranged power belt which is applied to the extent,

The belt-shipper may comprise any nary 0,115; itable means for engaging and ing theiii t, for examplma; belt-fork L, he belt-fork is carried by a slideK which is arranged for longitudinal adjustment along a line uniformly parallel with the counterordishaft, and preterably'formed by a rod or bar slide in a guide or hearing om supported to The guide or bearing for such the hanger. purpose may it may as illustrated consist of apende t bracket L bolted at 12 to the hanger and adapted toprovide separated guide or beating portions 13 for the adjustable shipper rodv or slide which carries the fork as afor said.

As a means for adjusting shipper rod or slide is provided wlth smack M which is engaged by a inion N, so that by operating said pinion the belt-shipping device comprising the fork and its ad3ustable support can be moved for the [)lllDOSOPfit-Shlfting the bolt. The spindle 14 of the Simon N, is connected with a pendent lian le 0 by means of a toggle or universal joint P in which way an operator can from different positions turn the handle so as to shift the belt,

The rackand pipion movement employed for shifting the ligltshipper permits the same to be shifted to any desired extent, and hence the same can without change be employed widths of belting.

With further reference to the adj nstment of the shaft-hanger and its desired position, it is understood that the locking device can be arranged to permit the shaft-hanger to hang vertically should such position be do- It will be observedhowever, that by sustaining the shaft-hanger in an inclined position, its further upward swing will serve to the hanger, the
